From computers, tablets, and smartphones to cars, homes, and public transportation, our world is more digitally connected every day. The technology required to support the exchange of massive quantities of data is critical. ...

Dartmouth scientists and their colleagues have found that periphyton—a community of algae, bacteria and other natural material living on submerged surfaces - is helping to transform mercury pollution from a Superfund site ...

EPFL researchers have shed new light on the fundamental mechanisms of heat dissipation in graphene and other two-dimensional materials. They have shown that heat can propagate as a wave over very long distances. This is key ...

Pick up a handful of sand, and it flows through your fingers like a liquid. But when you walk on the beach, the sand supports your weight like a solid. What happens to the forces between the jumbled sand grains when you step ...

Here's the rub with friction—scientists don't really know how it works. Sure, humans have been harnessing the power of friction since rubbing two sticks together to build the first fire, but the physics of friction remains ...

Research teams from Paris, Madrid and Berlin have observed for the first time how magnetic domains mutually influence one another at interfaces of spintronic components. Using measurements taken at BESSY II, they could demonstrate ...

Prof. Gustau Catalan has published in Nature Materials a commentary on the measurement of negative capacitance presented by the teams led by Prof Sayeef Salahuddin and Prof. Ramesh in the same magazine. The study detects ...

Using natural gas for car fuel is a challenge, requiring massive research efforts to find materials that can efficiently store it. However, a Swiss-US study concludes that the best materials have not only been already discovered, ...

Multitasking circuits capable of reconfiguring themselves in real time and switching functions as the need arises—this is the promising application stemming from a discovery made at EPFL and published in Nature Nanotechnology. ...
